I spent 3 years and 80000 miles with the 170 diesel and is the only reason I choose the GTD, for the engine.
Having had two A3's in the last six years I felt like a change...I was tempted with a 123d but with the necessary options, it pushed 31k and another £110 per month. GTI's are great but so are GTD's. Cruise along at 80mph in top next to a GTI then floor it and the GTD aint left wanting. The A3 had DSG, its great, but flawed, specially when your pushing hard on B roads, tight bends and around roundabouts; I chose a manual this time and am sure I've made the right choice.
Looking forward to seeing pictures of the tattoo Kev, although I'm not holding my breath......
When I feel the need for speed, I ride my motorbike, 0-60 in 3.2 seconds, 0-100 in sub 7; fast cars are too expensive in comparison. The bike only cost £7500 (although with extras cost £9k)
